Hazardous and Toxic Waste Disposal Technologies

John Huang, Ph.D., PE and John Poullain, PE

This two-hour online course provides general guidelines for the engineered disposal of hazardous and toxic waste (HTW) at uncontrolled hazardous waste sites. The guidelines are intended for the selection of remedial actions and treatment of hazardous waste contaminants by constructing and operating waste landfills. Landfills present two types of environmental risks. Potential mismanagement of reactive, ignitable or incompatible wastes could result in fires, explosions or toxic fume releases. Leachate, runoff or wind erosion can contaminate the subsoil, groundwater and nearby surface water. Remedial actions performed at a contaminated site must comply with federal and state regulations.

The student will become familiar with the general guidelines and techniques for the design and installation of land waste disposal areas and deep well injection systems used for the disposal of hazardous waste. Deep well injection is considered as an optional method to land disposal. Basic design elements of landfills, advantages and disadvantages of landfill disposal systems and consideration of the specific site conditions to assure sound engineering solutions in order to forestall problems or litigation are discussed. The methods and basics of incineration and thermal desorption methods and their uses for disposing of contaminated material in waste landfills are also discussed.

You are required to study chapter 4, paragraphs 4-20 and 4-22, and chapter 5 of the US Army Corps of Engineers Manual, “Technical Guidelines for Hazardous and Toxic Waste Treatment and Cleanup Activities”, EM 1110-1-502 (1994 Edition, 25 pages) and the Course Introduction paragraph. All material for this course is in PDF file format.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
